HOT WATER SUPPLY OPERATION
Ignition
Press ON/OFF Button of Remote Controller to turn on unit and the remote control-
ler display and priority LED will light up.
When a hot water tap is opened the Water Flow Sensor revolves and sends a pulse
signal to the Printed Circuit Board (PCB.) When the PCB detects water flow it be-
gins the ignition process with the Combustion Fan Motor starting first.
Once the air proving is made the Main Solenoid Valve and Change-over Solenoid
Valves are opened and the Burner is lit by the sparking Igniter.
Temperature Setting
With the Temperature Control Buttons on the remote controller the outlet tempera-
ture can be set from 37 - 60℃.
Temperature can not be set higher than 48°C while hot water is in use.
Standby
When the hot water tap is closed the PCB no longer receives a pulse signal from the
Water Flow Sensor. The PCB shuts the Main Solenoid Valve and Change-over So-
lenoid Valves and the Burner extinguishes.
